Two patients, aged 18 and 47 years, with ictal vomiting during temporal lobe seizures documented with bilateral depth electrodes are reported from the Department of Neurology, New York School of Medicine, Hospital for Joint Diseases, New York. Vomiting developed when the seizure discharge spread to the right temporal lobe of one patient. In the other patient who was left-handed and had right-hemisphere language dominance, ictal vomiting was associated with a left temporal discharge. These cases supported the localization of ictal vomiting in the nondominant temporal lobe. [1]

COMMENT. The authors cite 16 previous reports of ictal vomiting, the first dated 1982, with right temporal foci in 14. In a 1955 report from the Children’s Medical Center, Boston, 33 children with cyclic vomiting, 7 (21%) having a history of complex partial or generalized seizures and 25 (76%) with seizure discharges in the EEG, some focal with temporal localization, were thought to have a form of epilepsy [2]. Ictal vomiting is discussed in Progress in Pediatric Neurology I, Chicago, PNB Publ, 1991, pp46-47.
